To tu ZIJ/wm, t mn/y concern:

Be it known that I, HENRY Bacone, a citizen ot the United States,residing at Springfield, in the county of Clark and State v of Ohio,have invented certain new and useful Improvements in Corn-Harvesters,or" which the following is a specification, reference being had thereinto the accompanying drawings.

1o My invention relates to corn-harvesters,

and more particularly to the conveyers employed in such harvesters forcarrying the cornstalks which have been cut through the guideways to therear of the machine, where they are received upon. a platform; and theobject of the invention is to provide a con-- veyer of this characterwhich will carry the stalks through the guideway and withdraw from thesaine without interfering with the 2o stalks immediately following thearm.

A further object is to provide such a conveyer that will be positivelydriven and the action of which will be certain and etlicient.

In the drawings, Figure l is a plan view oi 2 5 the machine embodying myinvention in one form. Fig. 2 is a rear elevation of the same. Fig. 3 isa side elevation of the lower portion of the conveyer, and Fig. 4 is asimilar view of the upper portion of the conveyer.

3o The present application is a division ot` the application iiled by meMay i4, 1906, Serial No. 316,644, and in the drawings I have illustrateda machine embodying my invention in one form, in which l is the main 3 5frame of the machine, supported at its opposite ends on ground-Wheels 2and 3, ot which 3 is the drive-wheel and which is provided with asprocket 4 and sprocket-chain 5, passing around the sprocket 6 on thedrive-shaft 7. This frame is provided at its forward end withgathering-in arms 8, of any suitable character, provided withgathering-in conveyers 9, adapted to carry the stalks et corn back tothecutting mechanism 10, which is located at the rear of the gathering-inarms, both the gathering-in conveyers and the cutting mechanism beingoperated through suitable connections from the driving-sl'iaft 7, all ofWhichforms no part of the 5o present invention and is not shown 1ndetail,

but' is included in another application.

The frame l is provided with a de'ck or loor portion 11, supporting themechanism herein described. Mechanism is provided for conveying in anupright position the severed stalks thus delivered by thegathering-conveyers at the iront orn the machine, said. conveyingmechanism carrying the stalks to the rear ci' the machine and theredelivering them to the tender or shocking- 6o receptacle. The conveyingmechanism comprises two curved upright guides 38 and 39, arising fromthe platform 1I, their iront ends extending forward to and embracing therear ends of the gathering-conveyers l0.

'These guides are supported by uprights or posts 40 at their front andrear ends, and the inner guide 39 is slotted horizontally, as indicatedat 41, to permit the passage ot the conveyer-arms. These conveyer-arms(in- 7o dicated by the reference-numeral 42) are shown in the presentinstance as comprising two groups composed of three arms each, althoughobviously the number of groups and the number of arms in each group maybe varied. Each group of conveyer-arms 42 is mounted on a rock-shaft 43,supported in vertical position in bearing-arms 44, which projectradially from the top and bottom of the portion of the conveyer-shaft 23which 8o extends above the bearing-sleeve 45 of the bracket 24. Therock-shafts 43 are moved to different positions by means of a fixed cam46 to cause the conveyer-arm 42 to project into operative positionacross the guide- 8 5 way formed between the guides 38 and 39 and towithdraw or retract said arms to permit them to clear the tender and therear supporting-post 40 of the inner guide 39.

The cam46 is secured to the bracket 45, 9o and the lower ends of therock-shafts 43 are provided with arms 47, secured thereon and carryingantitriction-rollers 48, adapted to bear against the margin of the cam46. The rock-shafts 43 are acted on by springs which 95 serve to holdthe rollers 4S in contact with the cam 46. The arrangement I prefer forthis purpose is that shown, in which each rock-shaft has coiled on itbelow the upper cross-arm 44 of the conveyer-shaft 23 a roo spring 49,one end of which is secured to a collar 50, fast on the rock-shaft,while -the other end bears against the arm 44 in such a way as to tendto rotate the rock-shaft 43 in the proper direction. In order to preventthis spring from turning the rock-shaft on which it is mounted too far,each rock-shaft is provided near its lower end above the lower cross-arm44 with a stop projection or linger 51, secured to a collar 52, which isfastened to the rock-shaft by means of a setscrew 58, as is also thecollar 50. This stop prevents the spring from throwing the arm 47 pastthe central line connecting the rockshaft 43 and conveyer-shaft 23 whenthe roller 48 is at the point of minimum eccentricity of the cam. Saidroller is additionally guided by means of an outer guide-flange 54,extending along this portion of the cam parallel with the marginthereof, said guideflange being carried by a bracket or plate 55,secured to the under side of the cam 46.

The operation of the device as herein described. will beobvious. As thecornstalks are fed by the gathering-in conveyer past the cuttingmechanism and between the upright guides they are pushed forward by theouter ends of the conveyer-arms, these arms being held in extendedposition by the roller carried by the guide-arm and bearing against theface of the fixed cam. As these arms travel in a circle, they follow thepath of the curved guide and carry the cornstalks steadily forward untilthey reach a point near the rear end thereof, when the roller passesover the angle in the cam and allows the arm to drop back on its pivotto a position parallel with the frame and transverse to the movement ofthe cornstalks, and in this position it is withdrawn from between thestalks without interfering with the onward movement of the same.

I wish it to be understood that I do not desire to be limited to theexact details of construction shown and described, for obviousmodifications will occur to a person skilled in the art.

Having thus fully described my invention, what `I claim as new, anddesire to secure by Letters Patent, is

1. In a device of the character described, the combination, with a mainframe having cutting mechanism and upright guides forming a guidewaythereon, of a conveyer provi ed with pivoted arms adapted to extendacross said guideway, and a fixed cam acting to change'the angularposition of the arms as they approach the rear of the main frametofmaintain said arms in substantial parallelism with the transverseaxis of the main frame, whereby saidv arms clear the frame and arewithdrawn lengthwise from contact with the stalks to prevent moving thesame laterally, substantially as described.

2. In a corn-harvester of the character described, the combination, withguides forming a guideway for the stalks, of a reel comprising avertically-revolving conveyer-shaft having arms secured thereon,rock-shafts mounted in said arms, conveyer-arms on said rock-shafts, afixed cam, and traveling arms secured to the rock-shafts and bearing onsaid cam, said rock-shafts bein provided with springs to hold thetraveIing arms against the cam and with stop-arms to limit thespring-actuated movement of the rock-shafts, substantially as described.

3. In a device of the character described, the combination, with theguides forming a guideway, of a conveyer comprising avertically-revolving shaft, a hub carried thereby, radial arms securedto said hub, conveyerarms pivoted to the outer end of said radial armsand adapted to extend across said guideway, and means for controllingthe position of said conveyer-arms with relation to said guideway tomaintain said arms at substantially right angles thereto and to withdrawthe same lengthwise from the stalks to prevent moving the samelaterally, substantially as described.

4. In a corn-harvester of the character described, the combination, withguides forming a guideway for the stalks, of a conveyer comprising avertically-revolving shaft, a series of hubs on said shaft, radial armscarried by said hubs, conveyer-arms pivotally secured to the outer endof said radial arms and adapted to extend across said guideway, meansfor controlling theposition of said conveyer-arms relatively to saidguideway to maintain said arms at substantially right angles thereto andto withdraw the same lengthwise from the stalks to prevent moving thesame laterally, substantially as described.

5. In a corn-harvester of the character described, the combination, withguides forming a guideway for the stalks, of a conveyer comprising avertically-revolving shaft, a series of hubs carried thereby, radialarms secured to said hubs, rock-shafts mounted in said radial arms,conveyer-arms carried by said rock-shafts, collars secured to saidrock-shafts, arms mounted on the lower end of said rock-shafts, rollerscarried by said arms and engaging a -cam to control the movement of saidconveyer-arms, and springs surrounding said shafts and having one endengaging said collar and the opposite end bearing against theconveyer-arm, substanstantially as described. i

In testimony whereof I aflix my signature in presence of two witnesses.
